Genome-wide analysis of the "cut-and-paste" transposons of grapevine.

<h4>Background</h4>The grapevine is a widely cultivated crop and a high number of different varieties have been selected since its domestication in the Neolithic period. Although sexual crossing has been a major driver of grapevine evolution, its vegetative propagation enhanced the impac...
